With this rear wheel, a VanMoof X3/X4 with a defective e-shifter (Error 44) can be converted to the automatically shifting A2K system from Sturmey Archer.

This is the same hub that was ultimately used in the VanMoof A5.

This rim is extra strong due to an extra thick wall of 3mm (instead of the standard 2mm)
The disadvantage of this is that the weld is not completely clean.
